Greenroads, a rating system developed at the University of Washington to promote sustainable roadway construction, awarded its first official certification to a Bellingham project that incorporates porcelain from recycled toilets.

The Greenroads Foundation made the award last month to the Meador Kansas Ellis Trail project, which was recognized for doing things such as using low-energy LED streetlights, managing storm water with porous concrete, and accommodating cyclists and pedestrians.

The newly widened sidewalk also incorporates more than 400 recycled toilets, crushed into what the project engineers have dubbed – wait for it – "poticrete."

When project engineer Freeman Anthony with the City of Bellingham heard that a local nonprofit was replacing hundreds of toilets, he called up his regular ready-mix concrete company.
